Abstract

Aluminium phosphide tablet formulation that releases phosphine fumigant is widely used for insect control in various stored products. However, there is lack of data on variations in aluminium phosphide content in tablets of different brands as well as in their spent residues and phosphine content in spent residues. In tests conducted on four brands of aluminium phosphide tablet formulation manufactured in India, no significant differences in aluminium phosphide contents in unexposed tablets (56.4 to 58.6%) or in spent powder (3.1 to 3.6%) between brands were observed. The tablet released 1.1 g (range 1.0-1.2 g) of phosphine in 7 days. Each tablet produced about 3.57 g spent residues from which 0.1 7 g of phosphine was released at a slow rate over a period of 10 days in 10% sulfuric acid at 27 ± 3°C. No phosphine was released from spent residues by the recommended method of wet deactivation using water + detergent mixture, with any of the brands. The study revealed inadequacy of wet deactivation of spent residues with water + detergent mixture and stressed the need to avoid contamination of food commodities with the spent powder.
